Plugin Translation

Hi,
I have published https://wordpress.org/plugins/e-mailit/ plugin and nn the latest versions I have made code changes to enable plugin’s translation.
Unfortunatelly in https://translate.wordpress.org/projects/wp-plugins/e-mailit there is no stable version to be translated and in development version I can see only few available texts (in newer versions I’ve added much more texts).

What am I doing wrong?

Thanks in advance.
